Alexander Graham Bell was an inventor, scientist, and engineer. He is best known for inventing the telephone and co-founding Bell Telephone, which eventually became the American Telephone and Telegraph Company (AT&T). He was awarded the patent for the telephone on March 7, 1876. Three days later, he spoke the famous first words into his invention: “Mr. Watson—Come here—I want to see you.” His assistant, Thomas Watson, received the words in the next room, changing communications forever.

The reverse design features an early rotary dial telephone. The rotary dial contains the digits and numbers with “Telephone” in the center. Additional inscriptions read “MASSACHUSETTS” and “UNITED STATES OF AMERICA.” The reverse was designed by Eric David Custer and sculpted by Emily Damstra.
